ROUTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 5 14,010, dated August 6, 1895.

Application fil September 17,1894. Serial No. 523,228. (No model.)

To whont it may concern.- ing the plate in position thereon, as a sta- Beitknown thatLW'ILLIAM SPALOKHAVER, tionary clamping-piece 13 at one end of the .a citizen of the United States, residing at cylinder and a movable clamping-piece 14,

I have aimed especially to produce such is engaged by a worm 21 on a shaft 22, which a machine which shall be particularly well is operated by means of a crank 23.

As a full understanding of the invention Extending longitudinally of the machine, can best be had by a detailed description of parallel with the axis of the cylinder 12, to a machine embodying the invention in the the rear of and above the cylinder, is a rod preferred form, all general description will be 30, loose on which is-a sleeve 31, which serves 85 omitted, and such a detailed description will as a carriage for the tool-holder. The toolnow be given in connection with the accomholder is carried by an arm 33 extending forpanying drawings, in which ward from the carriage, and the outer end of Figure 1 is ajsideIelevation of a curved which arm serves as an operating-handle 34. plate routing-machine embodying the various By this construction the sleeve 31 being free 90 features of the invention. Fig. 2 is a front to slide and to rock on the rod 30 the carelevation. Fig. 3 is a plan view. Fig. 4 is a riage may be readily moved to carry the tool sectional detail showing how'the tool-holder in either direction in a line parallel with the is mounted. axis of the cylinder, and may also be rocked Referring to the drawings, A is a suitable to carry the tool down into operative position 5 frame by which the various parts of the maor up away from the cylinder. The downchine are supported. Carried by a shaft 10, ward movement of the tool-holder is limited mounted in suitable bearings 11 in the frame by a guide-bar 35, parallel with the rod 30, at each side of the machine, is a cylinder 12, which acts as a stopand rest for the arm 33, which forms a bed on which the plate to be op- A-ny suitable tool-holder may be employed. Ico 5o erated upon is mounted. The cylinder 12 is and it may be mounted in any suitable manprovided with any suitable means for securner. In the preferred construction shown the tool-holder proper consists of the spindle 40, having gripping-jaws 41, which are engaged and tightened by a screw-head 42 on the lower end of the spindle. The lower part of the spindle is journaled in a bracket or casing 43, and the upper part thereof is journaled in and held against longitudinal movem ent in asleeve 44, which sleeve is free to slide in the bracket or casing 43 and is raised and lowered by a screw 45, which passes through a lug 46 of the sleeve 44, said screw being journaled in the casing and being held against longitudinal movement by a collar 47 and extending above the casing to receive a hand wheel 48. The spindle 40 will thus be raised or lowered as the hand-wheel is turned in one direction or the other, while being in all positions free to rotate. A pulley 49 is splined on the central portion of the spindle, the casing being cut away to receive it, as shown. The bracket or casing 43 is free to slide on the arm 33 and is provided with a set-screw 2, thus providing for a backward and forward adjustment of the tool-holder.

The spindle 40 is driven by a belt 50, which, passing around the pulley 49, leads backward on each side to horizontal sheaves 51 and 52, carried by the sleeve 31, thence outward in either direction parallel with the rod 30, and consequently with the line of travel of the sleeve 31, to stationary vertical sheaves 53 and 54, and thence down to a driving-pulley 55, a guide-sheave 56 being preferably provided between the driving-pulley and one of the sheaves 53 or 54 to cause the belt to have a more extended bearing on the driving-pulley 55. By this arrangement of the belt the horizontal movement of the tool-holder by the sliding of the sleeve 31 on the rod 30 is not interfered with whether the belt is in motion or not, as the belt between the sheaves 51 and 53, on one side of the sleeve 31, and between the sheaves 52 and 54, on the other side of the sleeve 31, being parallel with the line of travel of said sleeve, the distance from one of the vertical sheaves, as 53, around the sheave 51, pulley 49, and sheave 52 to the other vertical sheave 54 is always the same, whatever the position of the sleeve 31 on the rod 30, the belt simply rolling on the pulley 49 and on the sheaves 51 and 52 when the sleeve is being moved horizontally on the rod 30. The belt also does not interfere with the desired vertical movement of the tool-holder by the rocking of the sleeve 31 on the rod 30, as the belt lies quite near the rod 30 in either direction from the sleeve.

The driving-pulley 55 is fast on a drivingshaft (50, mounted in suitable bearings 61 on the frame A and preferably having fast and loose pulleys 62 and 63 for the main drivingbelt, (not shown,) by which the machine is driven. A belt-shifter 04 is indicated by dotted lines carried by a rod 65, hung to the frame A and extending to the front of the machine within reach'of the operator.

The rod 30 and guide-bar 35 are preferably supported by brackets 70, pivoted to the frame A, as by being fast on a shaft 71, the ends of which are journaled in bearings 72 in the frame, and one or both of the brackets being provided with adj Listing-screws 73, which bear on either side of a lug 74 on the frame A, thus providing for an adjustment of the rod 30 and guide-bar 35, and consequently of the limit of the downward movement of the tool-holder, as, by swinging the brackets, the guidebar 35 will be moved nearly vertically, While the movement of the rod 30 Will be nearly horizontal.

The vertical sheaves 53 and 54 are preferably carried by brackets 75, adjustable on the extended endsof the rod 30, to providef0radjusting the tension of the belt 50. By having the sheaves 53 and 54 carried by the rod 30, on which is mounted the sleeve 31, by which the sheaves 51 and 52 are carried, the sheaves 51 and 52 will not be thrown out of line with the sheaves 53 and 54 by the adjusting of the brackets 70.

In operation, the plate to be operated upon having been secured on the cylinder, and the Worm 21 being in engagement with the wormwheel 20, and the various parts being properly adjusted, and the main driving-belt having been shifted to the fast-pulley G2 to start the tool rotating, the operator with one hand operates the tool by the handle 34, while with the other he operates the worm 21 by the crank 23 to rotatively move the cylinder or bed 12. When it is desired to rout, the arm 33 is held down against the guide-bar 35, and it may he moved longitudinally to carry the tool longitudinally of the plate, whether so held down or thrown up to move the tool away from the plate. By turning the crank 23 the cylinder is rotated, thus moving the plate transversely beneath the tool. Provision is thus made for a universal movement of the plate and tool relatively to each other, and the tool may be thrown into or out of cutting position at will. By holding the cylinder against rotation and moving the tool the tool may be made to cut in a straight line longitudinally of the plate, and by holding the tool and rotating the cylinder the tool will cut in a straight line transversely of the plate. By moving both tool and cylinder the tool may be made to cut in any desired direction.

The sleeve 31 and the parts carried thereby are preferably so arranged and proportioned that the tool will be normally held away from the plate, ora suitable spring may be provided for this purpose, if desired.

It will be understood that I am not to be limited to the exact construction or arrangement of the parts as shown, but that many changes may be made in the construction shown without departing from the invention; and it will also be understood that some of the features of the invention will be found useful and may be used with constructions differing widely from thatshown, and in themselves form part of the invention, as claimed.
